READING THE PERIODIC TABLE
OF THE ELEMENTS
Each square of the
Periodic Table
usually includes the
element’s name,
atomic number,
chemical symbol,
and atomic mass.

CREATE-YOUR-OWN (CYO) PERIODIC
TABLE (PT)
 Fill in the Key at the top for Carbon
 Follow my example on the board
 Begin filling in the atomic symbol, atomic mass, and
atomic number for the elements in BIG white PT —be
sure to use the same order as the key!
 If you didn’t finish the Life Science Vocab in CRT
Packet, then it is homework! If you need a book to take
home, you may check one out after school.
Periodic Table Crossword Puzzles
 Packet 9, Page 18 and 19
 Do your best from what you know, and use the periodic table
and process of elimination to figure out the rest!
 Oh….and it’s extra credit!

CYOPT – Write in
the “Metals”
Section
METALS
Almost 75% of all
elements are classified
as metals
Physical properties of
metals:
1. hardness
2. luster (shininess)
3. malleability (can be
pounded or rolled into
shapes or flat sheets)
4. ductility (can be pulled
out or drawn into wires)
5. Conductors (transmit
heat and electricity
easily)
6. Magnetic (attracted to
magnets)

ex. iron (Fe), cobalt (Co),
and nickel (Ni)
7. Most metals are solids
at room temperature
(high melting point)

Exception: Mercury (Hg)-liquid at room
temperature
GROUP 1: ALKALI METALS
1
GROUP 1: ALKALI METALS
 Group 1
 1 valence electron
 Causes skin burns if you
come into contact with it
 which it readily loses to become  Physical Properties:
a cation
 Extremely reactive – NEVER
found alone in nature
 Only found in compounds,
combined with other
elements
 Reacts violently with water
to produce explosions
 Soft- can be cut with a
plastic knife
 Shiny
 Lightweight
 Good conductors of
electricity and heat
 Low melting points
 Tarnishes rapidly
BELLWORK FRIDAY: 2/24/12
GROUP 2: ALKALINE EARTH METALS
2
GROUP 2: ALKALINE EARTH METALS
 Group 2
Physical Properties:
 Fairly hard
 2 valence electrons
 bright white
 2nd most reactive
 good conductors of electricity
group of elements
in the periodic table  high melting points
 high densities
 Chemically bond
very easily by giving Why called Alkaline? When
away 2 electrons
mixed in solutions =pH
greater than 7
 Those pH levels are defined as
'basic' or 'alkaline' solutions
GROUPS 3-12: TRANSITION METALS
3 4 5 6 7 8 9 10 11 12
GROUPS 3-12: TRANSITION METALS
 Groups 3-12
 Largest group of elements
 Most commonly found
elements
 Follows NO rules when
finding valence electrons
 Use the two outermost
shells/orbitals to bond
with other elements
 Most elements only use the
valence shell
 Physical Properties:
 Most are hard and shiny
 All are good conductors of
heat & electricity
 Are fairly stable, reacting
slowly or not at all with air
and water
 Most have very high melting
and boiling points
 Most dissolve in acids
(except Gold!)
 Most have luster
